Customized Barium Fluoride Single Crystal Windows

Barium Fluoride (BaF2) is similar to Calcium Fluoride in it's properties and is used for optical windows, lenses, and prisms, particularly when transmission into the ultraviolet is desired. The transmission range is from 0.2m m to 11m m. Transmission in the VUV is degraded by prolonged exposure to a moist atmosphere, but it is not significantly degraded by exposure to high energy radiation. Baf2 window is recommended for use a vacuum ultraviolet windows where high radiation resistance is required. Barium fluoride windows is less soluble than LiF, but relatively more solubie than MgF2 and CaF2.

Optical Baf2 window is less resistant to attack by water than Calcium Fluoride but attack does not begin until 5000C. In the dry atmosphere Calcium Fluoride can be used up to 8000C. Barium Fluoride is the most resistant fluoride to high energy radiation but does not have the VUV transmission of other types. The optical germanium windows is very sensitive to thermal shock.
